,To all 107mm t may concern.

lfBe it knownithat I, LEROY G. BINVKLEY. a citizen .of the United. States, residingat Chleago, lin the county yof Cook and -State of Illinois,have invented certain new and usefullmprovements in Mine-Car llVheels, of which the following is a specification.

rllhis invention pertains to car wheels andmore particularly to wheels of thetype .usedonmine ears which are subjected toextremely rough usa-ge.

In this type of car it is desirable that the for purposes of inspection, .repair or replacement of parts.

Onefof the primary objects of my invention .is to provide a wheel for the purpose mentioned which can be quickly and easily locked in running position and released for removal wheneverfoceasion requires.

AFor the purpose of facilitatingan.understanding ofmy invention, I have disclosed on the accompanying drawings, one .preferred embodiment thereof from an inspec- .tion of which, when considered in ,connection \with .the .following description, mylinvention and. many of. its inherentadvantages should be readily understood and appreciated. f

.Referring-.tothe drawings,- l l.Figure l is a .longitudinalsectional view y.through .a wheel structure embodying my invention;

Figs. .Q vand l3 are transverse seetional views .taken on the linesQ-Q and S-Srespectively; and Fig. 4 is a view similar toiFig. l, showing another .embodiment of my invention.

Byreference tothe drawings it wlllbeobserved that :reference character '5 indicates Lgenerally a bearing box for a mine ear adapted'to be securely attached .to the r.body of the -car by bolts -which `pass upwardly .throughthe openings provided inthe web The axle 7 projecting through 'the box, as shown, ex-

tends from sideto side ofthe car andjpro- I jects at its opposite sideithrough'a`boxsi1nilar to that shown. I It is be'lievedfhowever, that an illustration of the box and Aaxle structureatone side ofthe "car only willlbe sufficient Ifor an `understanding of 'my `invention.

Referring particularly to Figs. 1 .to inclusive, the core orbeari'ng portionS ofthe box throughwhich 'the axle'7 'projects -is slightl-yenlarged toward-the center of the box, as Tindiea'tecl by reference character 39, to receive a 'collar ll which mayfbe rotatably mounted on-the axle au'd held against longitudinal movement or it `may be rigidly atk tachedto a reduced portion ll2 ofthe axle by means of a pin 13, asshownaor lother preferred fastening means may be lemployed. This collar is provided at its inner-end'wiith a 4radially Vprojecting flange 14 fforming :in

l eliect .a shoulder on the axle. and f. this `flange projects Aoutwardly finto :the fbo'dy of the :bearing box and is provided on its inner -face with an :annular rib ll5 f which serves to hold against displacement the ,inner ends i of the :bearing :rollers 16 whieh are .interposed between :the axle Iand the surrounding hub 1710i fthe car wheel .18. Therouter ends of Vthe bearing -rollers are .retained y'in fposition anfannular,4 ring 19y preferably formed-"of sheet .metal and provided with lufgs --which niayr-be struck :radially inwardly itofengage in a .cireumferential.` groove 21 formed in .the eend of the .axle Lto holdxthe` ring in. position.

,The rollers, -therefore, -are held in .position on the 'axle bythe .1i-.ing .19 and the irib l5 v softhatfuponremoival .of the wheel the rollers remain ontheaxle inrpositionto be inspectedorv-repaired ifnecessary.

The .bearing box. an I.enlarged .core .forming an ,annular chamber 22, f as shown, adapted .to receive :the ,inner .end of vthe 'wheel hub` yso that .the lwheel .and the v.box :are ,disposed intelescopici rel-ation. The inuer wall: 28 lof the fbox is spaced .inwardly frein-the axle flangell .toprovidean annular .iace-way .24, shown, and .this..iaceV way serves to accommodate .the locking members which engage behind thez'flangelt and lock the wheel .rotatably againstlongitudinal displacement from the vaxle.

The means for effecting the .lookinglof the wheel against longitudinal displacement comprises 'a' plurality of bolts 25 .which `rare threaded intoatapped openings forined in sav radially projecting lugs or shoulders 26 *cast integrally with the wheel structure and disposed between the wheel spokes 27. The inner ends of Vthese bolts project into the bearing box beyond the flange la and are provided with radially projecting heads 28 which are adapted to be engaged behind the flange or shoulder la, as shown in Figs. 1

f and 3, to thereby hold the wheel against longitudinal displacement. These bolts, to

, insure their engagement behind the flange lll, are locked Aagainst. rotative movement by Vlock-nuts 29 threaded onto their outer ends where they are readily accessible so that they can be loosened witha wrench when desired. j

When removal of the wheel is required 'fol any reason the lock-nuts 29 are backed oli aV short distance, whereupon, by the applica- Voli `such length Vthat this rounded end will Vclear the inwardly projecting shoulder ,33

Y of the box so thatthe bolts arev free to be rotated through an arc of 180O into inoperative or disengaged position with respect to the flange. The wheel may thereupon be removed longitudinally of the axle and when it is replaced it can be quickly locked in position again by a half turn of the locking bolts and a tightening rupl of the loclnnuts 29.

To exclude the entrance of dirt into the bearing box the space between the lugs 26 is closed by an annular rib or web of metal 34 cast between these lugs, and the perimeter of this rib rotatably fits within the inturned outer edge of the box, thereby closing the Vouter end of the chamber 22 so as 4to precln de the entrance of dirt into this chamber.

The modification illustrated in Fig. l is Vsubstantially identical, so far as the wheel structure and -loclringfbolts is concerned,

with thatI just described, but in this instance instead of providing a vsleeve l1 which is fixed to the axle and carries the lockingv flange la, this flange, indicated in Fig. t by *reference character 36, is formed integrally with the box ,37 so that in this instance the wheel is locked te the bearing box instead of to the axle. The method of asseinbly 'of the wheel and the disengagement of the locking means for purposes of removal of the wheel are substantially the same as 'has been explained.

lt should be apparent from the foregoing that I have provided a wheel structure which embodies strength and durability and at the same time employs simple means for Vlocking the wheel in position, and while I It will be observed from` have shown and described for` purposes of illustration those embodiments of' my invention which at present seem preferable and most practical, it should be understood that the structure may be varied considerably without departing 'from the scope of the invention'as defined in the following claims.
